Johanna Jackson

Athletics, 20km race walk

5pm

The 27-year-old will compete for Great Britain in the women's 20km race walk on Saturday but will need the performance of a lifetime to get a medal. She finished 23rd in the world championships last year and was disqualified from the 2009 world championships in Berlin but became the first British woman to win a major race walk title when she picked up Commonwealth Games gold in Delhi in 2010. "I normally keep my goals and aims to myself but in terms of London I think I'm capable of top eight. I've had some injury problems but, if I'm fit and healthy, that is achievable," Jackson, who trains in Australia in the winters, said before adding: "It's every athlete's dream to win an Olympic medal and I do hope to achieve that one day." Perhaps that one day is today.

Mo Farah

Athletics, 5,000m

7.30pm

Farah already has a gold to his name after last Saturday's stunning win in the 10,000m race, when the Somalia-born athlete made history by becoming the first Briton to win an Olympic gold medal at the distance. The 29-year-old said that his heat felt like "being in the ring with [the GB boxer] Anthony Ogogo. As soon as they saw me there was a lot of barging and pushing." Farah, however, has been backed by Sebastian Coe and Paula Radcliffe to recover in time for Saturday night's final. "To bounce back to compete in the 5k is very, very difficult but he has shown us that he can do it," said Radcliffe. Farah admitted that the earsplitting support from the home crowd will help him. "If it wasn't for the crowd, I don't think I would have won the 10,000m," he said.

Ed McKeever

Canoe sprint, K1 200m

9.30am

Ed McKeever showed he is in good form as the 200m canoe sprint made quite a splash on its Olympic debut on Friday. Racing in front of a flag-waving crowd under sunny, cloudless skies at Dorney Lake, the barrel-chested McKeever proved he is one of the world's fastest kayakers by clocking the quickest time over the heats and semi-finals of the marquee K1. "It's been fantastic and the buzz you get when they announce your name on the start line and the roar you get, it's amazing," said McKeever, who crossed in 35.087sec in his heat and easily won his semi-final. McKeever was given an extra boost by seeing his arch rival Piotr Siemionowski, the world champion from Poland, fail to reach the final after finishing only sixth in his semi.
